Natural Gas?

Natural Gas?: A debate has raged for years as to whether natural gas is better or worse overall than coal and oil from a global warming perspective. The back-and-forth findings have been due to length of the studied time, the details of natural gas extraction, and the electricity-generating efficiency of various fuels. A new study from Cornell addresses this question by comparing the reduction of greenhouse warming that would result from substituting gas for coal and some oil to the reduction which could be achieved by instead substituting zero carbon energy sources. It was shown that substitution of natural gas reduces global warming by 40% of that which could be attained by the substitution of zero carbon energy sources. the study does not consider secondary considerations, such as economic, political, or other environmental concerns and focuses instead on global warming only.
